In the world of high-flow exhausts, size really does matter, and not just for the sights and sounds. Naturally, the components should fit together to work well.
A larger tip will give the engine a stronger, hearty sound, while a small tip will produce a raspy sound. This is where taking a look at different exhaust tips for your vehicle will pay off. You'll be able to determine the style and noise you're looking for.
Choose the right exhaust tips' size:
First, find the circumference of the pipe using a tailor's measuring tape (or a piece of string you can then measure with a standard measuring tape or ruler). Then, divide the circumference by p (3.14) to get the outside diameter.
Outside Diameter vs. Internal Diameter
There are two types of measurements to pay attention to when you’re working with tubing — the external diameter and the internal diameter. The external diameter is the distance from edge-to-edge, including the thickness of the tube itself. The internal diameter is the distance from edge-to-edge, not including the tube thickness. So, just the space inside.
